Using 3D photogrammetry models to identify wrecks

Using 3D photogrammetry models to identify wrecks

Tyler recently "re-identified" the Corsair that we dove last October. While we cannot be 100% sure, we are pretty sure based on accident reports that the original team mis-identified it (newer accident reports were released in 2012). In the search for more clues, Tyler started reviewing the photos I had taken. The "version" of the [...]

Sub Tower Photogrammetry Model & Videos (Catalina — 205 fsw)

I published the story and photos for the "Sub Tower" dive a little over a week ago. Docking ring on the sub tower I just published two GoPro videos of the dive along with a photogrammetry model of the docking station portion of the structure: Sketchfab Photogrammetry Model: https://sketchfab.com/3d-models/beaver-iv-sumbersible-test-tower-5b88a7b8ce8f42418039ddc3e5bb0b62 Sub Tower Photogrammetry Model Vimeo GoPro [...]

Piper Cherokee Photogrammetry Model (130 feet, Catalina Island)

Piper Cherokee Photogrammetry Model (130 feet, Catalina Island)

My primary goal when diving the Piper off Catalina was to practice my photogrammetry skills and have another project to explore some of the features and functionality of the Metashape software. I took a LOT of photos knowing that I would have overlap but I also didn't want to miss any key angles. This was [...]

Photogrammetry Technical Details & Equipment

Photogrammetry Technical Details & Equipment

Background I started hearing about photogrammetry for documenting and visualizing wrecks about 2-3 years ago and had a passing interest. Since then, I've spent more time working on my photography skills (and equipment). I had watched a couple Wetpixel videos on photogrammetry recently and decided that, with Covid, I should learn more about it. I've [...]

TBM Avenger Photogrammetry Model (San Diego, CA — 250 fsw)

TBM Avenger Photogrammetry Model (San Diego, CA — 250 fsw)

I debated whether or not to post this model. I'm not really happy with the results but I've learned quite a bit along the way and figured it might help somebody in the future. This post is pretty long but there are a lot of photogrammetry details included for anybody who cares. Short Version Here [...]

Photogrammetry – Part 3 (UB88 Project Dive 1/2)

Photogrammetry – Part 3 (UB88 Project Dive 1/2)

Intro / Background After diving the UB88 wreck a number of times and also starting to delve into photogrammetry, I decided to combine both of these into a rather large project: Build a realistic 3D Photogrammetry model of the entire UB88 wreck. This project represents a number of challenges -- starting with the fact that [...]
